<p>Look for qualified this usages in the same class.</p>
<p>Examples:</p>
<pre>
    Positive example 1：
    //org.apache.commons.lang3.concurrent.BasicThreadFactory
    ScheduledExecutorService executorService = new ScheduledThreadPoolExecutor(1, new BasicThreadFactory.Builder().namingPattern("example-schedule-pool-%d").daemon(true).build());

    Positive example 2：
    ThreadFactory namedThreadFactory = new ThreadFactoryBuilder()
        .setNameFormat("demo-pool-%d").build();
    //Common Thread Pool
    ExecutorService pool = new ThreadPoolExecutor(5, 200,
        0L, TimeUnit.MILLISECONDS,
        new LinkedBlockingQueue<Runnable>(1024), namedThreadFactory, new ThreadPoolExecutor.AbortPolicy());
    pool.execute(()-> System.out.println(Thread.currentThread().getName()));
    pool.shutdown();//gracefully shutdown

    Positive example 3：
    <bean id="userThreadPool"
          class="org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor">
        <property name="corePoolSize" value="10" />
        <property name="maxPoolSize" value="100" />
        <property name="queueCapacity" value="2000" />
    <property name="threadFactory" value= threadFactory />
        <property name="rejectedExecutionHandler">
            <ref local="rejectedExecutionHandler" />
        </property>
    </bean>
    //in code
    userThreadPool.execute(thread);
